Japan National Institute of advanced industrial technologies sustainable materials research department under the low load power sintered micro neodymium-Iron-Boron (NdFeB) powder, developed do not add dysprosium (Dy) also guarantees thatthe coercive force not reducing the density method for producing sintered magnet, and confirmed the validity. Relevant research results in March 2014, 21-23rd in Meguro-Ku, Tokyo and the Japan Institute of metals "2014 the speech to the General Assembly in the spring" published. Dysprosium is a rare earth metal, most made in China. Automobile manufacturers, without use of dysprosium can make a hybrid car and drive motors have a strong demand for electric vehicles.
